The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of six units of a flight-critical electrical control equipment component, identified by NSN 7R-6110-014522467-KB. This presolicitation notice indicates that the item requires Government source approval prior to contract award, as the technical data available does not support full and open competition, and only previously approved sources will be solicited. Interested parties must submit the necessary documentation for source approval along with their proposals, as offers lacking this information will not be considered. For further inquiries, potential bidders can contact Michael J. Zuccarini at (215) 697-1106 or via email at MICHAEL.ZUCCARINI@NAVY.MIL, with proposals due within 45 days of the notice publication.
